ject is brought about by movably supporting 15 the vertical track sections in which the door slides, in such a manner that the sections may approach and recede from the door frame.

The supporting means consists preferably of a series of brackets secured to'the frame and having slots which slo e downwardly to.- wards the frame. The oor has. pins-which ride in the slots. Springs are employed to connectthe sections to fixed points on the door structure, so that the sections are normally drawn upwardly and away from the frame. When the door comes into closing position, it engages foot plates at the lower ends of the track sections, and the weight of the door moves the sections downwardly and brings the door into contact with the frame,

with the result that the door opening is well.

sealed at the sides. Y

Reference to these views will now be made by use of like characters which'are employed to designate corresponding parts throughout.

The several figures illustrate a door frame 1 having brackets 2 secured to the sides thereof. Vertical track sections 3 are supported bythe brackets by means of pins 4 extending from the sections through slots 5 formed 'in the brackets and sloping downwardly towards the frame. Above the sections 3 is mounted a horizontal extension 6 of the track having curved ends 7 adapted to register with the upper ends of the sections 3' under circumstances presently to be described. A sliding door composed of sections 8 hinged ment in the tracks by means of rollers 10 carried by the hinges and received in said tracks. The upper ends of the sections 3 are joined by springs 11 to the branches 6 or to some other fixed part of the structure. In drawing the sections 3 upwardly, the springs tend to remove the sections from the frame 1, due to the action of the pins 4 in the inclined slots 5, as illustrated in Figures 3 and 5. I

' Thelower end of each section 3 carries an inwardly extending foot plate 12 engageable by the lower end ofthe door. The door proand when the door engages the plates 12, the

action of the springs 11 by the weight of the door: In moving downwardly, the sections 3 with the sliding door contained therein appreach-the frame 1, and the inner surface of the door is brought into contact with the frame as shown more clearly in Figures 2 and 4. By reason of this operation, the spaces which would ordinarily be retained between the door and the frame at the sides -thereof In Figures 6 to 9 is illustrated a modified construction wherein a firmer support, for

the movable track sections is provided. In this case the brackets 20;.secured to the-door frame 21 have two parallel slots '22 which slope downwardly towards the frame in the manner and for the purpose already described. The track sections 23 carry pins 24 passing through the slot, and the pins 5 moreover are fitted with rollers 25 within the slots. A plate '26 held loosely against eachbracket by the pair of pins passing therethrough prevents the pins from withdrawing. The operation of this device in other respects is similar to that described in connection with the other modification.

Although specific embodiments of the invention have been illustrated and described it will be understood that various alterations in the details of construction may be made without departing from the scope of the invention as indicated by the appended claims.
